118:8.6) For when culture advances overfast, when material achievement outruns the evolution of worship-wisdom, then does civilization contain within itself the seeds of retrogression; and unless buttressed by the swift augmentation of experiential wisdom, such human societies will recede from high but premature levels of attainment, and the "dark ages" of the interregnum of wisdom will bear witness to the inexorable restoration of the imbalance between self-liberty and self-control

(1302.3) 118:8.6 The slowness of evolution, of human cultural progress, testifies to the effectiveness of that brake — material inertia — which so efficiently operates to retard dangerous velocities of progress. Thus does time itself cushion and distribute the otherwise lethal results of premature escape from the next-encompassing barriers to human action.

(1302.4) 118:8.7 The iniquity of Caligastia was the by-passing of the time governor of progressive human liberation — the gratuitous destruction of restraining barriers, barriers which the mortal minds of those times had not experientially overridden.

(1302.5) 118:8.8 That mind which can effect a partial abridgment of time and space, by this very act proves itself possessed of the seeds of wisdom which can effectively serve in lieu of the transcended barrier of restraint.

(1302.6) 118:8.9 Lucifer similarly sought to disrupt the time governor operating in restraint of the premature attainment of certain liberties in the local system.

normal wiki world,

143.1.4 And no matter what blunders your fellow men make in their world management of today, in an age to come the gospel which I declare to you will rule this very world.

Urantia will become a jewel in the crown of Michael, our Master

And when the kingdom shall have
come to its full fruition, be assured that the Father in heaven will not
fail to visit you with an enlarged revelation of truth..." (1914:5)

"Urantia is now quivering on the very brink of one of its most amazing and
enthralling epochs of social readjustment, moral quickening, and spiritual
enlightenment." (2082:8)

Extremely unlikely, this world is the world of the Creator son micheal, its also the headquarter's of the archangel's, do you really think these beings are going to let the world go to hell?

That is exactly what Jews in Jerusalem were saying about the importance of their city and the temple in the eyes of God before Nebuchadnezzar came, destroyed the temple and burned it all to the ground.

Yes, the Gospel of Jesus will surely rule this world, in the ages to come --- there is no doubt about that.

As for the Creator Son and an Archangel and any other being that is involved in the management of this sphere's affairs --- they have no right whatsoever to interfere with the sacred freedom of will of mortals (bestowed by the Universal Father himself!) to do anything they wish, including blowing up themselves "to hell" if such is the degree of their utter insanity to which they have driven themselves through greed, hatred, envy and all other manifestations of materialism.

You correctly identify this planet as a sentimental shrine of all Nebadon --- but be consistent to continue to the logical point of the "shrine" (unless it is to become some useless relic, rather than an EDUCATIONAL tool for all the worlds of this universe, nay, maybe even the whole superuniverse) namely to clearly illustrate what will happen (i.e. a self-destruction of civilization) to the planet when its creatures reject the way of Light and Truth. The wages of sin are death and the wages of planet-wide rejection of truth is the choosing of falsehood (i.e. materialism) with the inevitable self-destruction attended thereupon.

There is no need for avoiding self-destruction in order to fulfill the prediction that "the Gospel of Jesus will rule this world". If this civilization is destroyed (or as TM'ers say euphemistically "population will be decimated to 1/10th of the present number") and some small part of it evacuated to a standby planet (as per John's prophecy of 144,000 in the book of Revelation) and then in a few hundred years return from there (as per the prophecy of the book of Enoch) to biologically uplift the surviving humans of this world (btw, "another" Adam and Eve may take part in this process, but that is purely my speculation) --- by that time a normal planet again, i.e. radioactive effects would die down. Then, the new society will be built upon better principles, not the materialistic ones of today. Then, and only then, the Gospel of Jesus can (and most surely will!) triumph.

What shall we say then --- give up trying to spread the Gospel of Jesus today? God forbid! Rather, do all we can to deliver the saving message of Jesus to all nations, work in the Lord's vineyard while it is still day, for the night is coming very soon when no man shall be able to work. The saving message is the fatherhood of God and the brotherhood of all mankind --- i.e. love and serve one another and be not mindful too much of the coming destruction of this world. There is nothing we can do about preventing it. But there is much we can do about bringing the peace and hope of survival to those mortals who otherwise would soon die in terror and despair and ignorance.
